Royale has frequently mentioned seeing the killing of Mark “Papa” Guardado, the president of the San Francisco chapter of the Hells Agels motorcycle club, from her front window on Sept. 2. She’s talked about it in debates, in interviews with reporters and even had a news conference to discuss it last week.

She said the reason she didn’t give her statement to police for 13 days was because neither the Mission District police station nor homicide inspectors returned her calls. She only spoke with investigators after police had named a suspect.

Police Sgt. Wilfred Williams said it’s really the other way around — police returned Royale’s call immediately and kept on calling.

“There were attempts to contact the witness, and there was no response,” he said. “The same day we received the information from the witness, the witness was contacted.”

Royale’s campaign manager, Antonio Salazar-Hobson, said he had no comment.
